Embodiment
Embodiment 1:
By hydrocracking with will separate (by underpressure distillation) from the content of wax intermediate product of hydrocracker and become last running and lighting end to prepare several different samples of Chevron 170RLV basestocks.Hydrocracking condition in the hydrocracking reactor is selected to constitute vacuum gas oil is converted into the product that contains cut in 30 weight % fall the content of wax between the 40 weight %.After separation, use the hydroisomerization dewaxing catalyst that last running and lighting end are possessed dewaxing, described catalyzer comprises the metal-modified SSZ-32X molecular sieve of magnesium, platinum hydrogenation metal and the alumina adhesive of medium hole dimension.
Show the Chevron 170RLV basestocks produced and the average behaviour of Chevron 110RLV basestocks below, seen Table I:
Table I
Embodiment 2:
Other party has been made the basestocks of the boiling range with 730-1000.3 examples are Yubase4, Yubase6 and Shell XHVI 4.0.Some performances that in following Table II, shown these oil.
Table II
All these the three kinds of basestocks manufacturings and the costliness of buy.Yubase 6 and Shell XHVI4.0 are III class base oils.The Noack volatility that Yubase 4 has is higher than the best required ratio of concocting with the ratio of the CCS VIS under-25 ℃.If Yubase 4 is added among the figure of Fig. 1, but though see of the requirement of its Noack volatility near the 5W-XX engine oil, its CCS VIS under-25 ℃ is more much lower than essential CCS VIS, and this causes concocting low and and the overspending of efficient.
Embodiment 3:
Tested 5 kinds of different III class basestocks and found that they have the performance shown in the Table III.These different III class basestocks be usually used in the blending of Chevron 220R or other II class base oil with those of the requirement of the Noack volatility that satisfies multi-stage engine oil and the CCS VIS under-25 ℃.
Table III
III class base oil typically gets up more expensive than base oil manufacturing of II class and purchase.In addition, when they were used for engine oil, they needed other test to satisfy the base oil interchange guidelines.
Embodiment 5:
Figure shown in Fig. 1 makes by following: select the different petroleum derivation Chevron basestocks of (having first basestocks and second basestocks) in pairs, measures every kind of basestocks at the CCS VIS under-25 ℃ and Noack volatility and drafting these points (first and second point) on x-y figure.Be prepared into concoction to the Chevron basestocks with various ratios, the CCS VIS under-25 ℃ that measures every kind of concoction is with the Noack volatility and use it for and make the curve that is connected and at first at second.For contrast, by the mode identical different with between Nexbase 3043, Nexbase 3060 and the Chevron 220 to drawing, concoct and make curve with paired Chevron basestocks.
Commercial engine oils now by will representing to satisfy all requirements under-25 ℃ CCSVIS and the point of Noack volatility chart, set the base oil requirement of 5W, 10W and 15W engine oil.These upward and to the general areas of 5W-XX, 10W-XX and 15W-XX are carried out mark as the little square table that adds to.
As finding out by figure shown in Figure 1, the curve between 110RLV and the 170RLV drops in the zone of 5W-XX engine oil exactly.This good predict that provides is, the 5W engine oil requires the available only concoction of these two kinds of basestocks to satisfy, and without any need for brewable material.Curve between 110RLV and the Chevron 220R drops in the zone of 10W-XX engine oil exactly.This good predict that provides is, the 10W engine oil requires the available only concoction of these two kinds of basestocks to satisfy, and without any need for brewable material.If expectation 10W-XX engine oil has the low CCS VIS-25 ℃ under or reduces by one in the Noack volatility or its both, then concocting Chevron 170RLV in the 3rd basestocks can be ideal.
Fig. 1 shows that also Chevron 220R can directly be blended in the 15W-XX engine oil under the situation that does not have second basestocks or brewable material.If expectation 15W-XX engine oil has the lower CCS VIS under-25 ℃, then Chevron 220R can satisfy these requirements with the simple concoction of a small amount of Chevron 110RLV.If expectation 15W-XX engine oil has lower Noack volatility, but then Chevron 220R and these requirements of simple concoction of Chevron 170RLV on a small quantity.The advantage that has is to concoct in 5W, 10W and the 15W stage motor oil all three kinds under not using any III class basis oil condition.Described advantage comprise the base oil cost of reduction, easier base oil exchange, less Engine Block Test and preferable blending efficient.
Curve among Fig. 1 between the II class base oil impale than small area, and the solution degree that the base oil of described curve and 5W, 10W and 15W engine oil requires has illustrated blending efficient.For Chevron 110RLV and Chevron 170RLV, 5W, 10W and the 15W prescription that can satisfy requires and does not introduce any Noack/CCS as the system with III class basestocks and excessively correct (overkill).Fig. 1 has also shown the relative activity and the stability of the basestocks constitution system with Chevron 110RLV and Chevron170RLV, that is, if more strict new prescription requirement then will most possibly needn't be made rapid change and realize this point.In other words, can need bigger composition to change, for example add other brewable material or different additive based on the system of III class.
